β-Variational autoencoder as an entanglement classifier
Nahum Sá, I. Roditi · Physics Letters A · 2021
We focus on using an architecture similar to the β-Variational Autoencoder (β-VAE) to discriminate if a quantum state is entangled or separable based on measurements. We split the data into two sets, the set of local and correlated measurements. Using the latent space, which is a low dimensional representation of the data, we show that restricting ourselves to the set of local data it is not possible to distinguish between entangled and separable states. Meanwhile, when considering both correlated and local measurements, an accuracy of over 80% is attained in the structure of the latent space.
